I like playing on the tv with the joycon, too. I don't have a pokeball thingy, though.
Guys, have I told you about my amazing new year's eve playing session yet?
I caught two shinies in one day
The first one was a shiny pikachu which even has pretty great IVs, since I was chaining pikachus for candy at the time. I think I'm gonna evolve that one at some point :)
The second one was a shiny Geodude that I just ran into completely randomly. After the pikachu just maybe half an hour earlier, I couldn't believe my eyes :D
So yeah, I had a very shiny new year's eve, fittingly ;)
